Title: Process for treating wood
IPC: B27K3/08
Filed: 1973-10-12
Abstract: 1444102 Treating wood DOW CHEMICAL CO 12 Oct 1973 [13 Oct 1972] 47892/73 Heading D1P A process for treating wood comprises preheating the wood by contact with the vapour of an aliphatic chlorinated solvent at 50- 125C under superatmospheric pressure, immersing the wood in a solution (preferably boiling) of a wood treatment agent in the same solvent under superatmospheric pressure at about the same temperature (50-125C) for 0.1-10 hours, draining the excess solution and reducing the pressure at least to atmospheric to vaporize the solvent contained in the wood. The solvent vapour pressure is preferably 1.1-5 atmospheres, and that of the solution up to 15 atmospheres. The wood is preferably seasoned, the solvent methylene chloride and the agent pentachlorophenol e.g. at a 2-10% weight concn. The process may be made continuous by the provision of a plurality of wood treatment vessels arranged to operate in staggered cycles so that the vapours from the boiling solution being used to impregnate wood in one vessel are used to preheat new wood in another vessel. A preferred system using three vessels having a common source of pressurised boiling solution, common condensing (high and low pressure) and solvent recycling means and a common solution make up tank, is described.

Title: Process for the production of carbon fibres
IPC: D01F9/16
Filed: 1970-10-16
Abstract: 1323765 Carbon fibres BAYER AG 16 Oct 1970 [17 Oct 1969] 49243/70 Heading C1A In a process for producing carbon fibres by extruding a solution of carbon containing, fibre forming material, converting the extruded solution to a solid fibrous material and then carbonizing it, the solution contains at least one fibre forming linear high polymer at a concentration of 0À001 to 2% by wt. having a degree of polymerization in excess of 2000, together with from 5 to 60% by weight of a carbon source comprising at least one carbonizable organic compound having a m.p. or softening point in excess of 80 C. and a degree of polymerization below 2000. The term "degree of polymerization" is defined as the number of individual molecular units which have to be connected to form the polymeric substance. The carbon source is preferably an organic substance which in a 10% solution has a spinnability of not more than 10 cms., where the spinnability is defined as: the length in cms of uninterrupted filament extruded at room temperature under a pressure of 0À5 atm. from a nozzle having a diameter of 400 Á and a length of nozzle duct of 14 mm. The carbon source is preferably an organic substance which after carbonization by heating at a temperature of below 2000C. but of at least 400 C. in an inert gas leaves a residue of 10% by weight of the starting material. The carbon source may be a monomer or polymer which has a degree of polymerization which is less than 50. Materials exemplified are starch, partly degraded starch, oxidized starch, dextrin, hemicellulose, a polymeric sugar derivative or cellulose derivative and many others e.g. alginic acid, pectin, methylpectin, casein, gelatine or fishglue or an organic acid which is capable of internal salt formation, or a sulphonic acid or a substituted sulphonic acid, e.g. glycocol or betaine, or the ammonium salt of a sulphonic acid. Lignin, lignin sulphonic acid, and salts of lignin are also specified. If the carbon source is a material with a m.p. or softening point below the temperature at which it carbonizes, then subsequent to being spun the fibre is subjected to infusibilization treatment before carbonizing. The said high polymer materials are exemplified as vinyl polymers or copolymers, polyolefines, polydienes, substituted polyethers or polythioethers, polyesters, polyamides, polypeptides polysaccharides and polysiloxanes. The extruded solution may be an aqueous solution. The spinning process employed may be a dry spinning process. The carbon fibres produced may be subjected to a graphitization step.

Abstract: 1, 076,160. Hydraulic motors. DOWTY ROTOL Ltd. Dec. 14, 1964 [Dec. 19, 1963], No. 50191 /63. Heading F1A. In a hydraulically-operated vibrator the spool 63, Fig. 4, of control valve 54 is caused to reciprocate out of phase with the vibrator piston 52 by. coupling it with piston rod 53 through a split annular leaf spring 69. One end of the spring 69 is rigidly secured to an arm 66 fixed to the rod 53 and the other end is connected through a linkage 73 with the spool 63. The effective circumferential length of the spring, and therefore the spring rate, is varied by angular adjustment of an arm 75 carrying a clamping screw 78. The position of the arm 75 may be indicated by providing graduations on the spring and a viewing opening 79 in the arm. Increasing the spring rate reduces the stroke and thereby increases the reciprocating frequency of the piston 52. The frequency may also be varied by adjustment of stops 64, 65 or by mounting a weight for movement with the spool 63. In an alternative embodiment, Fig. 1 (not shown), a straight leaf spring (38) is secured at one end to a support (37) connected through a block (13) to a reciprocating piston (18) and at the other end to a valve spool (31). The reciprocating frequency is varied by vertical adjustment, through screw means (44), Fig. 2 (not shown), of a block (46) surrounding the spring, and/or by varying the number of weights (39) attached to the spring. The block (13) may be fixed and the cylinder housing (11) reciprocated to vibrate a body attached to a flange (15).

Abstract: 1,137,288. Magnetic data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 10 Nov., 1966 [23 Dec.; 1965], No. 50346/66. Heading H3B. [Also in Divisions D1 and H1] A storage device is produced by forming a layer of green magnetic ferrite around a cylindrical substrate, surrounding this layer with a green non-magnetic ferrite, slicing both ferrites, and sintering the slices. The magnetic ferrite may be Fe 1 . 62 Mn 0 . 80 Cu 0 . 45 Zn 0 . 10 Bi 0 . 02 La 0 . 01 O 4  and may be prepared by ball-milling a mixture of Fe, Cu, Zn and Bi oxides, MnCO 3 , and LaFeO 3 , passing it through a 20-mesh screen, calcining at 650‹ C., remilling, passing it through a 325-mesh screen, and drying. The non-magnetic ferrite may be Fe 1  . 2 Mn 0  . 78 Cu 0 . 3  Zn 0 . 7 Bi 0 . 02 0 4  or Fe 0 . 8 Mn 1 . 48 Cu 0 . 2 Zn 0 . 5 Bi 0 . 02 O 4 . A barrier layer, e.g. of Mn 3 O 4 , Cr 2 O 3 , Mn 3 O 4 + Cr 2 O 3  or Mn 3 O 4 +ZnO, may be provided between the two ferrites. The substrate may be a nylon filament which may be coated with a release agent, e.g. colloidal wax in water, and removed by pulling from one end. The magnetic and barrier layers may be applied by passing a continuous length of the filament through a suspension of the material and then passing it twice through an oven (at 70‹ and 80‹ C., using a nitrocellulose-amyl acetate solution, and at 100‹ and 110‹ C., using an epoxy resin solution); this process is repeated five times and the filament is then passed through an oven (at 85‹ or 125‹ C. resp.) 10 times. The structure may then be similarly coated with the non- magnetic ferrite, and a number of such structures cast in a wax or polyethylene block; the filament is then removed, the block sliced, and the wax melted off by heating to 100- 125‹ C. Alternatively, the structures may be cast in a block of the non-magnetic ferrite, which is dried at 90‹ C. in the mould and then at 100‹ C.; the filament is removed; and the block is then sliced either perpendicular to or along the axes of the cores (in the latter case the two halves are turned through 90 degrees before firing). Firing may be effected in a Ni boat coated with Mn 3 O 4 , initially at 600‹ C. to drive off the binder, and then at 920‹ C. The magnetic layer may have an inner diameter of 3 or 4À5 mils.
